Fig. 7 y Y Referring new more in detalto thedev'ic as shown in the drawings, the invention includes a base'2 of concrete, or otherl suitable material, upon which an anvil 4 is supported, the latter being'of any preferred construction and having a top face 6 and a beveled upper edge 8. Secured to thebase 2 adjacent the anvil is a chute 10 for receiving fragments of a broken wheel rfrom the anvil and for discharging said fragments into a suitable pit, not shown.

At opposite sides of the anvil are placed uprights 12 and 14 which, in the instance shown, are supported by cross-pieces 16, the ends of which are secured to upright columns 18, as clearly shown yin Fig. 2; the crosspieces being bolted, riveted or otherwise secured to the uprights 12 and 14, whereby said uprights are maintained in akrigid manner in their predetermined spaced relation. The uprights 12 and l14 are preferably of such form as to provide guideways fora hammer 20 and a tong housing 22, and, in the present instance, are I-beams, as shown in Fig. 3. The tong` housing 22 is' formed of oppositely disposed member's24, which may be castings, arranged back to back,and having flanges 25 extending between thecords of the uprights 12 and 14 to be guided thereby A(see Fig. 3). The members 24l arepr'ovided with apertnred lugs 26`through which a `lifting pin 28 eX`` tends (see Figs: 1,2, 7 and' 8)'Y and, further,

are provided with apertured lugs 30 whichv receive pins 32 forv pivotally mounting the ton`gs34; Vthe latter including the elongated handles 38 andgrabends 40. The members tion to form the housing, bolts 3G.

The tong housing, andfhence the'tongs, is raisedby means of a cable 42 connected to a socket 44 securedto the tong housing by'rods 46, the lower ends of which are connected toA the lifting pin 28, as shown clearly in Figs. 7 and'l8. /Vhile the arrangement shown and just described provides a'satisfactory connection of the cable 42 with the'tong housing, it is to be understood thatthis disclosure is merely illustrative, as, obviously, the cable 42 may be connected tothe tong housing in any'preferred or desired-manner within the spirit and scope of the present invention.

` atfthe'lower'endsof the cables l80 to which The cable 42 extends upwiardlyhandY isV ar-V ranged over a sheave 48 mounted'in'bearings Y y 50 supported by'I-beams 51 secured to oppofsitely arranged channels '62 extending between.. and connected to uprights 12 andV 14,

and saidV cable 42 extends over and is rconnected to a sheave 54mountedon aIiaXle 56, which latter is supported 1n bearings 58 ona frame comprising spaced horizontal I-'beams and the verticalcolumns 61; the forward..v

` ends of thebeams 60 being Ysecured tocone of and bracing members 67 thecross-pieces 16, as shown in Figs. 1 and 2. The frame further comprises guard-rails to provide, a rugged structure.

n becuredi to the inner channels 62 are trip- `blocks64 which areadapted to be engaged byy thefhandles 38 of the tongs whereby to spread they grab ends 40 of thetongs as here- 20,

inafter tobe described. y n

The hammer 2 0y may assume any desired forIn,but,iin.the `instance shown, includes ay head 66 providedpvvith a vhorizontal rib 68 on eachside thereoffto furnish a means by which the grab ends 40 of the tongs mayenygage thehammer.` to. elevate the latter.

ormally` arrangedy immediately over the anvil and in a position to surround a Wheel to be broken, is Aa cage provided with reinforcing ribs'72and with lugs 74,' to which latter are secured the lower ends of lifting elements indicated generally at 75. l These lifting Velements are preferably flexible and,

. inthe' instancejshown, include cables 80 and chains 76; counterweights 78 being provided the ,'upperends ofthe chains 76 areL secured.

The upper endsof the-lifting elements 75,y

more particularlyrthe'upper ends vof the cables 80, are connected toy sheavesy 82 mounted outside of the uprights 12 'and1'4 respectively, on a shaftl-84, supported in bea-rings 86, carried'by bracketsy 88, mounted on and secured to supportingbars arranged acrossl f thefuprights .12 and 14,as clearly rvshown in,y Fi Adjacent the lower ends of -theuprigrts'r l12 `and 14 areoppsed angles 92, the! inwardlyl extending legs 94 thereof` serving asguides forthe counterweights 78, they latf terfbeing provided with slots ontheir side edges to receive 'the-legs 94 of said angles, as.`

clearly shoWni n'Fig.,.3-. .y 'y n n, In the operation ofthe device, asv will be hereinafter pointed. out, the cage is elevated and'loweredto itsrk normal position prior to lthe completion of the elevation of the ham mer- 20, `and kit is necessary that the. cage re-V mainfinV normal position vsurrounding the wheel to .be broken until after the hammer yliasldropped onto the wheel, and, to effect this, the lifting elements lare so arranged that a slight slackis provided therein, more particularly at the lower ends thereof. The

lower ends ofthe` lift-ing elements 7 5. might, 'of course, be cables, similar to the cables 80,

' support/ed, due to the membersO l. n The frame formed ofthe members 60 sup-l ports theoperating or actuating devices. for

or the lower ends of said lifting elements may assume various forms, but, to'provid'easimple arrangement, the lower ends ofthe liftin elements have been indicated as chains. eferring now to Fig. 1,- it can be seen that` one portion of the cage 70 knorn'rally Aseats or rests onlzthe anvil whenxit in its] lowered position, While another portion is not directly to which lthe lower end of a supporting rod 95 fis securedas-by a clevis 97, the rod extending c through an eye 99 secured to a cross-,piece'16. The upperend of the rod 95 is threaded to receive adjusting nuts. 101, ,whereby the .cage may` be ,properlyk adjusted'to prevent 1 any binding thereof with the uprights 12 and14. rThe shaft 84, yhereinbefore mentioned,carz

that thereduction gearin s. 114 and116 may eveled edge 8, and, to insure tliefproper positioning of the-cage, the :latter is provided With'anxa'pertured lug 93,

bearings k on Atheframe Y beconnected by means o any suitable coue y pling. In some cases, it may beadvisable ,tok use amanually operated clutch', and for thisreason, the `connector 115 has beeny shown as a clutch. Y The second reduction gearing 116 drives a pinion 118 which is in mesh with a large gear120emounted on the shaft 108 heretoforementioned. The shaft V108 carfv riesy the crank 106 at one end thereof, and'its other end-isprovidedwith a crank 122having ailink 124 carried thereby, to which one i end ofk a sprocketl chain .126, vis connected.

The opposite end v of .thesprocketv chain* k126 is-.arranged over and secured toV [a gear n,128 mounted on the end of the shaft 56;,heretoforev mentioned. A Thepin 104 carried rby. the Vcrank 106V has pivotally connected thereto one end of actuating rod 130, theerother end of whichzis connected to a safety mechanism indicated*generallygin' Fig. 3,Kat'132, and which is pivotallyconnected at134'to a pin 135carried; by a crank 136 `securedfto one end of a shaft 137 arranged in bearings 138 attachedto the frame meme.,

cured. The lever 144 maybe of any preferred form, and carries a bracket 146 at its lower end to which a link 148 is pivotally connected, as at 150; the opposite end of the link being pivotally secured at 152 to a pusher carriage 154 mounted on rollers 156 which ltravel on rails 158. The carriage 154 is of suitable form and at its forward end is provided with a pusher 159.

AsV will be pointed out, the carriage 154 recipro'cates toward and from the anvil, and is movable forwardly to and over a wheel slide 160, the pusher 159 being adapted to force a wheel, which has been placed on the slide 160, on to the anvil 4.

The wheel slide is shown in section in Fig. 2, and may comprise a casting having a longitudinal depressed area 162, the depressed area being provided with longitudinal s wear-stripsr 166 serving as rails over which the rollers 156 travel during the movement of the carriage 154, and flanged sides 164, the casting or wheel slide extending to he anvil,as clearly shown in Fig. 1.

The wheel breaker of the present yinvention is actuated by anA electric motor 112, and electric wiring is indicated at 168, but, inasmuch as the particular electricv circuits form no parts of the present invention, they are not described in detail. Suffice tosay, that a main starting switch 17 0 is provided for no-rmally starting and stopping the motor, and, further, the safety mechanism 132 is yincluded for the purpose of breaking the circuit and stopping the machine in an emergency. In addition, it will be notedv that during operation of the ymachine of the present invention, there is a normally closed electric circuit which is` automatically broken by the safety mechanism, hereinafter described, bythe continued operation of the machine upon the stopping of the pusher lever occasioned by its encountering an abnormal resistance; all as more clearly pointed out hereafter.

The safety mechanism isfclearly indicated in Figs. 4, 5V and 6, wherein it can be seenthat the extension rod 181, which, in practice, is pinned, as at 133, to the rod 130, extends through spaced spring seats or followers 172 and 174, respectively, said followers being provided with bosses 176, between which followers springs 178 and 180 are concentrically arranged. VAs clearly shown in Fig. 5, the springs 178 and 180 are of different tension, spring 178 beingseated in the recess defined by the bosses, 176, while the bosses themselves serve as 'seating means for the concentric spring 180 arranged around the rod 131. rlhe threaded end of rod 131 is provided with a nut 182, or other suitable backing means, for the plate 172, and the plates 172 and 174 are' connected by tie-bolts 184 extending through said plates and'through the ends 186 ofabifurcated connector 188, the outer end of which later is ring shaped, as at 190, to engage the pin 185. l

Intermediate the ends of the rod 131 a threaded portion 192 is provided to which a nut 194 is secured for an obvious purpose. The connector 188 is provided with a longitudinal recess 196 which receives the free end of the rod 181, as clearly shown in Fig.

6. Also, as shown in this F ig. 6, the rod 181 adjacent its free end is provided with an annular recess 198, the walls of which are Vbeveled. as shown at 200. The conhector` 188 is provided with tapped lugs 202 to which vertical posts 204 are secured. In the instance shown in the drawings, particularly Fig. three posts 204 are shown, although obviously this is merely by way of example, and said posts support a plate 206 from which a switch box 208 depends. The connector 1881s also provided with an apertured lug 210, the end of which is normally closed by a plug 212l having a central aperture therethrough in which plunger214 is mounted; the plunger being normally urged in a downward direction by a spring 216 and having a head 218 seating on the ball 220. 11s clearly shown in Fig. 6, the spring 216 retains the plunger in spaced relation to the push button 221 of the switch bor; 208, and alsoserves to retain the l' all220 in contact with the rod 131. During normal operati-on of the device, the ball is received or seated in the recess 198 of the rod 131. The switch bei; 208 is of suchforni that, pon actuation of the plunger 214, thedriving circuit for the machine ofthe present invention will be broken and the machine therefore stopped automatically. Plunger 214, it will be apparent, is actuated by movement of the rod 131 relative to the connector 188, whereby the ball 220 is forcedup either of the bevels 200 on to the periphery of the rod 181.

in operation, assume the parts to be arranged in the position shown in full lines in Fig. 1. car wheel to be broken is indicated 228, the same being'placed on the wheel slide 160, as shown in dotted lines in.

Fig. 1. The machine is now ready to operate to break a wheel. rlllie main'starting switch 170 is then actuated. The/switch 170 may be an 'ordinary push button switch or any preferred Vtype of switch. Closing the circuit by the switch 170 will start the motor 112 which will drive the reduction gearings 114 and 116, and hence the pinion 118, which latter will rotate the large gear 120 in a counter clockwise direction. Rotation of the gear 120, it is apparent, will rotate the shaft 108 and actuate the cranks 106 and 122. Rotation of the crank 106 will pull the cable 98 to turn the shaft 84, which latter will turn the sheaves 82 and elevate the cage 70 to clear the anvil V4. lVliile this action is taking place, it will be apparent that the crank 122 will be rotated counter clockwise, this ver y permitting the tong vhous`i1ig22 to descend by gravity, `due to the weight ofy said hous,Y

ing, and, while so doing, of course, the sheave 54 Will be rotated, turning the shaftl 56 andY the gear 128. Because'of the weight of the housing 22,1thev cable 42 Willbe prevented from jumping ofi' of sheaves48 and 54.`

When thehousing 22 reaches substantially .its lowest position, the tongs will engage the weight and, at this` time, the crank 122 will Y have completed approximately one-halffof one revolution, or Willhavetraveled about 'y 1809. 'Preferablythe cable 42 is of such lhigher than if it were y"resting directly on the anvil and the cable 42 is long'eiiough to permit the tongs to graby the hammerat its lowest possible position. Continued rotation of vthe gear 120, and hence crank 122, will re- .verse'the direction of rotation of the gear 128, which will obviously rotate the ysheave 54 similarly and elevate the tong housing and the tongs will elevate the hammer 2O.` The ing this movement,'the crank 106 is actuating f the crank 136,v through the medium of the rod 130, forcing the crank 136 rearwardly to turn shaft 137, and therefore movelever 144 and n the pusher forwardly to the extreineforward position and push the wheel onthe wheel slide 160 on to the anvil 4.y Continued rotan ,tion ofthe gear l120 causes the crank 106 to complete its rotation, f 'withdrawing` theI pusher159toy its vnormal position. The cage,

it is apparent, will descend by gravity. It can be jseenthat the counterweights 78 will continue to. descend after the cage is seated;

,that is, when the ycage'is in normal position V the, ydistance which the counterweights de# scend Vbeing commensurate with the length" of cable 8,0. AThe lifting elements are of such -length as topermit a slight lslack therein vcage lifting elements 75, particularly in the"y when the cage is in normal position, ,and the counterweights provide a means Aforv retaining the .cables '80,and hence thefcable 98, taut.` This provides a variable slackin the chains 76, to eifect a dwell inthe operation ofthe cage. vBy this is meant that the cage f ispermitted to remain in normal positiony i around awheel to be broken a predetermined time, `sufficient to allow the hammer yto operate beforethe initiation of the next sucn cessive lift or elevation of the cage. j While the counterweights 78 'are'descending,f thel handles;138 of the tongs engage the tripblocksv 64 to release the tongs from their en'- gagement with thev hammerand ,permit the hammer tofallon to the wheel to break the" same, the wheel fragments being prevented from'scattering byv the cage.

'From the above descriptiom'it isbelieved apparent that` the 'operation of the machine Awill be fully understood bythose. skilled inV Y the art. i

movementV of thelever rod 130 is therefore n againstan element which is'tending to lremain stationary. If the jam is suiiicient, it is apparent that the rod 131 will move in the recess v 196, whereupon th'efballv l22() will be urged upwardlyto actuate the plunger l214 which, in turmwill act on ,the button 221 to-break the circuit for'the `machine and thus stop the Y It is possible, ofcourse, that an emergency latter from'further operation until thejam has been relieved. machine at this time, it'can be seen, has thev v ,cage elevated, or, to ybe more exact, the cage andhaminer 2() are being simultaneously'ele'y vated, whereby to clear the anvil, and, dur.
